The various people in the lives of the Project Leda clones.
- Played by: Jordan Gavaris"You do realize I'm gonna have to paint this to come to terms with it?"
Sarah's foster brother and most steadfast ally. Like Sarah, he's a petty criminal, but he prefers his art. He plays an important role in protecting the clone-sisters and providing support.
- Beware the Nice Ones: He can have a rather cruel side when pushed; just look at his torment of the now brain-damaged Rachel after Sarah goes missing.
- Big Brother Instinct: He has this for Sarah.
- Big Little Brother: He is Sarah's (adoptive) younger brother and is clearly taller than her. He is also slightly taller than his biological half-sister Adele (he's 5'10, while Sarah and Adele are respectively 5'4 and 5'9).
- Camp Gay: Felix is so fabulous it almost hurts. Still, he's a sympathetic character, as opposed to being a two-dimensional stereotype.
- The Confidant: He's Sarah's support system and the only person that the clones trust. Deconstructed in season two, when he grows frustrated with having to help Sarah with her problems while trying to managing a personal life that is constantly disrupted by the various conspiracies.
- Cool Uncle: To Kira.
- Deadpan Snarker: Amidst all the violence, conspiracy theories and general chaos of his own life and that of everyone he cares about, he's always on hand with a sarcastic quip about it.
- Foolish Sibling, Responsible Sibling: Felix is the more responsible sibling, pointing out the flaws in Sarah's plan to impersonate Beth and that her constant roving will eventually mean she could lose custody of Kira. Even Sarah knows this. As the series goes on, he even starts playing this role with Alison to an extent, as part of his general Only Sane Man position within the family.Sarah: You are the best of us.
- Friend to All Children: He's surprisingly good with kids, though somewhat unorthodox. When babysitting Alison's kids, they have a lot of fun crossdressing.
- Gene Hunting: He started looking for his birth family between season 3 and season 4.
- Hooker with a Heart of Gold: His main job is art, but he works as a male prostitute when he has to.
- In-Series Nickname: Sarah calls him Fee. At one point, Helena calls him "brother-sestra".
- The Lancer: He is Sara's most consistent ally and confidant.
- Loveable Rogue: Though to a less extent than his sister, he has a criminal record as a thief and con artist. He does occasionally point out to Sarah that she is by no means the only hustler in the family.
- Masculine Girl, Feminine Boy: With his sister Sarah.
- Mr. Fanservice:
- A scene where Felix is wearing an apron. And nothing else. And is seen from the rear. He does this again in season 2, this time while painting a model!
- The season 2 premiere has him at a gay club wearing backless pants.
- Non-Action Guy: Nowhere near as physically strong as other characters, so typically acts as the brains while others are the brawn. Lampshaded towards the end of season three, when he rebukes Sarah for this and insists on kicking down a door himself. He gets it on the first go, surprising both of them.
- Odd Friendship: Develops one with Alison (and, to a slightly lesser extent, Cosima) over the course of season 1.
- He also develops one with Krystal in seasons 3 and 4...sort of.
- Only Sane Man: Generally assumes the voice of reason and practicality among Sarah and the rest of the clones.
- Papa Wolf: When Vic says he wants to get to know Kira, he absolutely refuses to let him anywhere near her.
- Parental Substitute: He's been something of a father figure for Kira, so when Kira's biological father enters the picture, he doesn't take it well. In fact, he flees in tears.
- Perky Goth: Technically a punk but otherwise fits the trope perfectly.
- Secret Keeper: The only non-clone in Clone Club. At least, until Sarah decides to let Art in on the secret.
- Shirtless Scene: In the first episode.
- Starving Artist: Subverted. His paintings don't appear to sell well, but he supplements his income with prostitution, theft, and cons.
- Team Dad: The one who frequently keeps the Clone Club in check.
- Took a Level in Badass: In the Season 3 finale, he kicked down a hotel door to get to Mark and Gracie. Even he can't quite believe he pulled it off.
- Undying Loyalty: Why else would he have stuck by Sarah all this time? Every now and then he expresses his frustration with what he needs to put up with, but never seriously looks like walking away from it.
- What the Hell, Hero?: Usually the first to call Sarah out on her less savory actions. He's also perfectly willing to call out Alison and Cosima when he feels it necessary.
Victor "Vic" Schmidt
- Played by: Michael Mando"This isn't over, Sarah."
Sarah's drug dealer ex-boyfriend, also known as "Vic the Dick". He's obsessed with Sarah, and refuses to let go.
- Ambiguously Brown: He's "urban," according to Alison.
- Bastard Boyfriend: His abusive treatment of Sarah is the reason she ditched him. Vic's obsessiveness to win her back doesn't help his case.
- Butt-Monkey/The Chew Toy: He takes a lot of abuse. So far, he's lost a finger to gangsters, received a beating from Paul and was pepper-sprayed and tasered by Alison.
- Character Development: Apparently, he's become a Buddhist, and becomes friendlier to Alison. Unfortunately subverted: he's actually spying on her for Angie, as part of a deal to avoid going to jail.
- Celebrity Paradox: Alison mentions Breaking Bad in Season 3. His actor is one of the main characters of its canonical Spin-Off, Better Call Saul.
- Chuck Cunningham Syndrome/Demoted to Extra: Disappears after leading Art and Angie to Alison, and is no longer part of the main cast as of Season 2.
- The Bus Came Back: After being absent for the first half of season 2, he returns to join Alison in rehab.
- Domestic Abuse: Has hit Sarah it the past, though she hits back.
- The Dragon: For Alison's Season 2 Story Arc, with Angie as the Big Bad.
- Entitled to Have You: He all but demands that Sarah give him another chance.
- Fingore: He lost a finger as punishment for losing the bag of cocaine.
- HeelFaith Turn: He apparently became a Buddhist in season 2, though its unclear how much of it is genuine and how much is just part of his cover.
- Hopeless Suitor: He really thinks that he has a shot with Sara. Key words, really thinks.
- It's All About Me: He is incapable of thinking about other people.
- He makes Sarah's faked death entirely about him and the pain it causes him, not even giving a damn about Felix.
- He also keeps barging into Sarah's affairs for his own satisfaction, despite the fact that she doesn't love him and that he always makes things worse for her.
- Even his apparent befriending of Alison is just part of a deal to avoid jail time.
- Karma Houdini: However badly he's been injured for continuing to interfere with Sarah's life, he still got away with the $20,000 from the cocaine Sarah initially stole from him. And he has yet to answer for inadvertently leading the cops to Alison.
- Jerkass: He's a rude, self-centered bully.
- The Lost Lenore: Deconstructed. He cares more about Sarah when she's "dead" than when she's alive.
- Manly Tears: Breaks down in tears (several times) when he finds out that Sarah's "dead". Interestingly, he isn't displayed sympathetically because of this, since he is a Jerkass and Butt-Monkey.
- The Mole: Angie's using him to find out more about the clones from Alison, in exchange for his charges being dropped.
- Pet the Dog: He tells Allison's kids to stay in school (and by extension, to not end up like him) after he loses a finger to the mob.
- Put on a Bus: Disappears from the series after Season 2.
- Spanner in the Works: By chance he runs into Alison thinking she's Sarah as part of a new con. He threatens to ruin the whole clone conspiracy due to his petty vindictiveness.
- The Thing That Would Not Leave: Hangs out at Felix's place drinking after Sarah's funeral. Felix draws the line when he mentions that he wants to get to know Kira.
- Token Minority: Lampshaded when Alison describes him as "urban".
- Tropaholics Anonymous: When we last see Vic in the season 1 finale he's at a meeting. However, he's not on-board with the "making amends" part of the program so he sells Sarah out to the cops, unintentionally outing Alison to Art in her place.
Siobhan Sadler (née Malone)
- Played by: Maria Doyle Kennedy"Tell them you're with Siobhan Sadler."
Sarah's Irish foster mother, who has a lot of skeletons in her closet. She raised both Sarah and Felix and now Sarah's daughter Kira.
- Action Mom/Never Mess with Granny: Implied, considering she keeps a shotgun. Confirmed in S02E02, when she kills two Birdwatchers who sold Kira out to the Proletheans, and again in S04E07 when she takes her revenge on Duko.
- Alliterative Name: Siobhan Sadler.
- Animal Motifs: Birds. Her hobby is bird-watching and she's part of a faction called the Bird Watchers. She also calls Sarah "Chicken" (as an affectionate nickname), has a swan art piece in her house, and took care of a man with many birds in his house.
- BFG: She keeps a double-barrelled shotgun by her side for protection.
- The Caretaker: For Ethan Duncan, who's hiding from Leekie.
- The Chessmaster: She turns out to be the one behind Kira's disappearance. She also has something to do with Project LEDA, but her connection to it has yet to be revealed in full.
- Further Chessmastery is demonstrated in 2.07 when she sets Leekie and Rachel against each other.
- The Confidant: Sarah and Alison decide to trust her with their secret. Incidentally, she actually knows more about them than they do.
- Crazy-Prepared: She has a number of defenses and escape routes in place should anything happen to Sarah, Felix, or Kira, as well as a network of friends and associates to call upon for help. She describes her system as bulletproof.
- Dark and Troubled Past: By her comments in season 2, it's implied she was involved with the IRA by gun running for them. And then there's her ties to Project LEDA and hiding Ethan Duncan from Leekie.
- Eating the Eye Candy: Does this to Paul. And later to Cal. And then again when she sees both of them."Just look at the two of you. I don't know how she does it."
- Face Death with Dignity: Remains calm and level headed in her final moments.
- Friendly Sniper: Episode 2x02 shows she's quite handy with a rifle.
- The Gunslinger: With her aforementioned double-barrelled shotgun.
- Jack Bauer Interrogation Technique: Uses it on Duko after capturing him. This appears to be the first time in the entire run of the show that the usage of this trope has actually produced useful information, though it remains to be seen whether everything he said was truthful.
- Kick the Son of a Bitch and/or Pay Evil unto Evil: When she tortures and then kills Duko, it comes off as this. He killed her mother and was a Smug Snake through and through so it was satisfying to watch, but he'd also been subjected to the same kind of blackmail that Alison was subjected to and seems to have been mostly a Punch-Clock Villain, so it's a bit dark to say the least.
- Killed Off for Real: Killed by Ferdinand late in Season 5, although she manages to take him down with her.
- The Lost Lenore: Her late husband, John Sadler, was killed in a drunken brawl. With her mother, as it turns out. Her mother regretted this and outright states that she brought Siobhan and Sarah together as atonement. They reconcile late in Season Three.
- Mama Bear: At first, she tries to keep Kira and Sarah apart to protect Kira because she doesn't think Sarah is a fit mother. She chills out slightly in episode four.
- Episode 1.07 reveals that she moved to Canada, even though it meant completely starting over, to hide Sarah from something that was looking for her in England. Special notice to the fact that she didn't even know what that something was; she went on the hunch of a friend. Though that may be a lie.
- In 2.02 it's revealed she kidnapped Kira to keep her safe from the Neolutionists and the Proletheans. When the two people she's working with turn out to be moles for the Proletheans she kills them without hesitation.
- Also inverted. After reconciling with her mother, Siobhan becomes very protective of her.
- MayDecember Romance: Her mother's dialogue in Season 3 heavily implies that Siobhan was still underage when she hooked up with her late husband. This pissed-off Siobhan's mother so much that she killed him.
- The Mole: The first finale reveals she may have been one of the scientists involved with creating the clones in the first place. It later turns out to be more complicated than that..
- Mutual Kill: She and Ferdinand shoot each other.
- Obi-Wan Moment: She dies calmly looking at a picture of Sarah and Felix, tearfully muttering the word "chickens".
- Only Known by Initials: She's almost always called "Mrs. S." or just "S". The audience doesn't learn her full name until 1.08.
- Parental Substitute: For Sarah, Felix, and Kira.
- Revenge Before Reason: In line with most people associated with the Real IRA, S follows a particularly brutal kind of code that Sarah describes as "black Irish revenge shit." After Duko kills her mother, she does not stop until he's dead, no matter the cost. She only slows down once she knows Sarah's plan will guarantee her an audience with Duko. And boy does she ever get it.
- Secret Keeper: And man, does she have a whole lot of 'em.
- Taking You with Me: After Ferdinand fatally shoots her, she quickly returns in kind.
- What the Hell, Hero?:
- Organized her house being ransacked and Kira's disappearance to protect Kira. But she did this without bothering to tell Sarah and Felix first, leaving Sarah extremely pissed off at Mrs. S. To make things worse, she planned to leave with Kira and go back to the UK.
- Gets another one in the series two finale when she arranges to have Helena kidnapped by the military. In her defence, this may have been the only way she could have freed Sarah and Kira from Dyad, but she herself acknowledges that Sarah will probably never forgive her for this.
- Widow Woman: Her husband's long dead by the start of the series. He was actually killed by Siobhan's mother.
- You Killed My Mother: Duko was never going to get out alive after doing that.
- Your Terrorists Are Our Freedom Fighters: She is framed as a mostly heroic fighter against oppression despite being strongly implied to be a former member of the Provisional IRA.
- Played by: Skyler Wexler"I think something bad is going to happen again."
Sarah's intelligent and open-hearted 8-year-old daughter. She went to live with Mrs. S. when Sarah disappeared.
- Adorably Precocious Child: Very smart for her age.
- Creepy Child: She's a little too calm and oracular for someone still in grade school.
- Guile Hero: Kira must have gotten it from her mother.
- While hiding with her father under assumed names, she charms a police officer to ward off his suspicions.
- While in Dyad custody, she pickpockets a cellphone off a nurse and sends Cal to Mrs. S. so they can collaborate on an escape plan for herself and Sarah.
- Healing Factor/Made of Iron: Was relatively fine not long after being run over by a car. Sarah's worried that being experimented on made her pass this (and potentially less beneficial things) to Kira, and the doctor's reaction to her X-rays suggests that Sarah's worry might be true.
- Heroic Bastard: Sarah never told anyone about Cal so Kira did not meet him until she's 8 years old.
- In-Series Nickname: Sarah and Felix called her "(Little) Monkey". Helena dubbed her "Angel".
- Little Miss Con Artist: Shows shades of this due to traits picked up from her mother and uncle.
- MacGuffin Super Person: Being the biological daughter of a clone makes her a very important scientific specimen from the Neolutionists' point of view. It's not clear yet how the Proletheans see her, but the fact that the Neolutionists want her is enough to warrant their interest. Mrs. S. alludes she's part of "Project LEDA", along with her mother Sarah. It also turns out that her stem cells are the only means of treating Cosima's autoimmune disorder.
- Morality Chain: Implied strongly that Sarah would be a much worse problem if she didn't have her daughter anchoring her.
- Morality Pet: To Helena.
- Nom de Mom: She uses Sarah's surname instead of Cal, even after she finally meets her father.
- Oracular Urchin: One of her first scenes has her drawing a picture of Sarah with blood pouring from her mouth.
- Parental Abandonment: She has a less-than-ideal home life.
- Pastimes Prove Personality: She's constantly drawing and painting, and has the associated personality traits: genteel, sensitive, and perceptive. Though her art is about as good as you'd expect a little kid's to be. Her favorite subject seems to be her family and she likely got it from her Uncle Felix.
- Protectorate: For Sarah, Mrs. S, Felix, and Helena. Neither Alison nor Cosima know her very well, but both care about her very much.
- Put On The Bus: In season 3 Sarah sends her to Iceland with Cal for her own safety.
- Sherlock Scan: She's very perceptive, especially for a little kid. She could tell Alison was impersonating her mother right off, that Helena wouldn't hurt her, and that Cal was her biological father.
- It's strongly implied that she can tell all the clones apart on sight, regardless of how they're dressed.
- The Stoic: An unusually young example. Nothing fazes her.
- Not So Stoic: When Daniel tries to kidnap her in 2.03, she screams for her mother, sounding more desperate and terrified by the second.
- Sympathy for the Devil: The only person who sees past Helena's terrifying and homicidal behaviour to the troubled child who was forced to learn that behaviour as a survival tactic.
- Telepathy: By Season 4, it's becoming more and more apparent that her ability to tell what the clones are thinking at a given time is more than just intuition.
- Wise Beyond Their Years: She displays a great understanding of the situation even though the adults try to preserve her innocence. Helena actually calls her an "old soul" to Sarah, when advising the latter precisely to share her clone-related worries with Kira. Also see Sherlock Scan above.
- Played by: Melanie Nicholls-King"How can two fates be so different? You two are like night and day."
Birth mother to two of the clones, who hails from Cape Town, South Africa. She emigrated to the UK and was hired as a surrogate by a "couple" who were really Neolutionists. After realizing the children she was carrying were to be part of a medical experiment, she escaped and gave birth to the twins, then gave them up.
- Blood from the Mouth: While she's dying.
- Chocolate Baby: She's black and her birth daughters are white. Justified as she's a surrogate.
- Mommy Had A Good Reason For Abandoning You: She had to give her daughters up because she couldn't take care of them.
- Genre Savvy: She always seems to know when someone's up to no good.
- Luke, I Am Your Father: She is Sarah and Helena's birth mother.
- Missing Mom: Is this for Sarah and Helena until 1x09. Then she dies in the next episode.
- Small Role, Big Impact: Only appeared in two episodes, but in those episodes she confirmed not only her relationship with the main protagonist, but also the protagonist's relationship with one of the (then) antagonists that will define most of the series.
- Walking Spoiler: Discussing her reveals that Sarah and Helena are twins among the clones.
- We Hardly Knew Ye: Was killed by Helena in the first season finale.
- Played by: Michiel Huisman"I didn't know your mom had any sisters."
One of Sarah's past lovers, and Kira's biological father. He first appears in the second season.
- Badass Beard: Has impressive facial hair.
- Carpet of Virility: And chest hair.
- Dark and Troubled Past: Implied. He had a hidden, fully stocked RV, untraceable money, and fake IDs before Sarah brought the clone conspiracy to his door. Either he's a Crazy Survivalist, or he has a reason to have to be able to disappear on a moment's notice.
- Disappeared Dad: He is one to Kira, but in his defense he didn't even know Sarah was pregnant when they broke up.
- Erudite Stoner: He's a genius inventor living semi-off-the-grid in a nicely furnished cabin, and a police officer who is a friend looks the other way regarding weed growing in his backyard.
- Even the Guys Want Him: Felix fawns over on how large his biceps are.
- Farm Boy: He currently lives in a pad on a farm.
- Hunk: Michiel Huisman isn't exactly unpleasant to look at.
- Gadgeteer Genius: He was an inventor before his partners forced him out and sold his tech to the military. Now he lives alone on a farm outside a small town.
- Good Parents: To Kira, when he finally meets her.
- Iconic Sequel Character: Does not appear until Season 2.
- Mr. Fanservice: It seems you'd have to be to get involved with the series' Ms. Fanservice.
- Nice Guy: After briefly and justifiably being angry with Sarah for scamming him when they first met, he's enormously helpful to her and in protecting Kira
- Offscreen Breakup: Word of God says he and Sarah amicably parted ways between Seasons 4 and 5 due to personal differences, hence Cal's Long Bus Trip.
- Old Flame: To Sarah.
- Papa Wolf: He threatens to shoot Daniel if he tries to take Kira away.
- Put on a Bus: In Series 2, Huisman prioritized this show in his schedule over Game of Thrones. In Series 3 it was the other way around, resulting in Cal being sent into hiding along with Kira. While Kira comes back, Cal doesn't. He doesn't even earn a mention in the finale.
- Tall, Dark, and Handsome: He stands 6 feet tall.
- Played by: Julian Richings
An old friend of Mrs. S's who occasionally helps out.
- Flat Character: Mainly exists as extra muscle for the good guys and a means for the plot to facilitate Kira's kidnapping.
- Good All Along: His first few scenes make it appear as though he's the one who kidnapped Kira and has sinister plans for Sarah. Later its revealed that he was just working for Mrs. S.
- Iconic Sequel Character: Does not appear until Season 2.
- Red Herring Mole: The 2.09, Rachel plants evidence to make it look like he was The Mole, but it was just a ploy to distract Sarah.
- Satellite Character: To Sarah and Mrs. S.
- Played by: Alison Steadman"Hell of a twist of nature, isn't it?"
Siobhan's estranged mother, Sarah and Felix's (adopted) grandmother. She's the original for both Project Leda and Project Castor.
- Bizarre Human Biology: She's a genetic chimera; she absorbed her twin brother in the womb, and thus has two sets of genes, male and female.
- Boom, Headshot!: Duko shoots her in the head and burns her body.
- Character Death: In 4.06, she is shot and her body is incinerated by Martin Duko on the orders of Evie Cho.
- Dark and Troubled Past: She did time for aggravated murder. There, she was used as a test subject by the Duncans.
- Face Death with Dignity: She doesn't flinch in the face of her imminent demise, instead telling Cosima her last words and insulting her captors while doing so.
- Long-Lost Relative: Siobhan hasn't spoken to her mother in years due to her killing Siobhan's husband, so Sarah doesn't meet her until the penultimate episode of season 3.
- Iconic Sequel Character: Does not appear until Season 3.
- Ill Girl: She has leukemia, and this becomes a plot point because it gives Cosima and Scott a chance to isolate the Leda genome from the Castor genome.
- MacGuffin Super Person: Since she's the original specimen of both Project Leda and Project Castor, a lot of different factions want to get their hands on her. Evie Cho eventually murders her to make sure the cloning projects become obsolete.
- Nerves of Steel: Stranger broke into her house? Guns pointed at her? Someone threatening to burn down her house? Kendall doesn't even flinch. She doesn't even break down knowing she's seconds away from death; she just tells Cosima not to cry because Cho and Duko aren't worth the salt.
- Never Mess with Granny: She threatens Sarah with a knife for breaking into her home, and shows no fear when a gun's pointed at her face — twice.
- Obnoxious In-Laws: She never liked Siobhan's late husband, John Sadler. She ended up killing him.
- Samus Is a Girl: Everyone assumed the Castor original would be an old man, but she's actually an old woman with male DNA.
- Screw Politeness, I'm a Senior!: Kendall is more than a little rough around the edges.
- Walking Spoiler: She basically started this whole plot with her very existence. Her two sets of DNA were used to create Project Leda and Project Castor.
- Played by: Lauren Hammersley
Felix's American biological half-sister with the same father, introduced in Season Four after he decides to find out more about his biological family. Her presence initially introduces some tension between Felix and Sarah, but they get over it.
- The Alcoholic: Obviously.
- Bunny-Ears Lawyer: Shows up to counsel clients drunk and gives every indication of being a hick, but she ultimately turns out to be an extremely capable attorney.
- The Bus Came Back: After leaving in Season 4, Adele returns in Season 5 after Mrs. S. recruits her into Clone Club.
- Functional Addict: She pounds back alcoholic drinks like they're soda pop and even mixes them with mood stabilisers, but thus far it doesn't seem to have impaired her abilities as a lawyer much, if at all. It's Played With in that showing up to court drunk has apparently gotten her license suspended in the States, though.
- Genius Ditz: Again, she is much, much more capable than she looks at first. She does seem to be a bit lacking in common sense though; she gets a bit aggressive with Helena and Felix has to get the latter to back down.
- Hello, Attorney!: She's a lawyer and quite attractive.
- Hooker with a Heart of Gold: Not presently, but she offhandedly mentions that she has moonlighted as a sex worker in the past.
- Internal Reveal: In Season 5, Siobhan lets her in on the secret and invites her into Clone Club.
- Locked Out of the Loop: Felix doesn't tell her about the clone conspiracy because it would place her at risk and because it's not purely his secret to tell. She thinks Alison, Sarah, and Helena are triplets (well, she's partially right, since Sarah and Helena are twins).
- The Mole: Sarah initially worries that she might be a Neolution plant and might not be Felix's real biological sister. It appears to have been subverted as it's revealed after a few episodes that she is definitely Felix's biological sister; furthermore, after almost a season on the show she does not appear to have any nefarious motives, and if her confusion about the clone conspiracy isn't real, then that's some damn good acting.
- Screw This, I'm Outta Here!: Partially on Felix's advice, she decides to get out of town for awhile at the end of Season Four after she finds out just how weird Felix's circumstances are.
- Southern-Fried Genius: Is very, very Southern, and turns out to be quite a capable attorney, if a bit of a Bunny-Ears Lawyer.
- Statuesque Stunner: She's a cute and ditzy woman who stands 5'9, the third tallest woman in the series.
Det. Arthur "Art" Bell
- Played by: Kevin Hanchard"Just follow the bloody brick road."
Beth's long-time partner on the force. He's one of the first people to notice something wrong with "Beth".
- Action Dad: Mentions in passing that he has kids. We meet his daughter Maya in the season 4 premier.
- Badass Beard: Has a goatee and is one of the most badass characters in the show.
- Badass in a Nice Suit: Due to being a detective, he's always slickly dressed.
- Bait-and-Switch: The first three episodes of the series made him look like an antagonist. He isn't and mellows by the fourth.
- Blackmail: Steals the money that Sarah took out of Beth's account and holds it over her until "Beth" gets back on the force.
- By-the-Book Cop: Subverted. He holds the money over Sarah-as-Beth's head because he helped Beth make the Maggie Chen shooting look like an accident.
- The Confidant: Becomes this to Sarah once he sides with the clones.
- Even the Guys Want Him: Felix thinks his ass his great.
- Fair Cop: Kevin Hanchard is pretty easy on the eyes.
- Forced into Evil: In season 5, with Dyad threatening his daughter and a Neo agent assigned as his new partner, he's essentially forced to negotiate between the Neos and the Clone Club with only snippets of rebellion.
- Friend on the Force: He is the Clone Club's main ally inside the law. Unlike Beth, he's not shown to be swallowed by the whole thing.
- Genre Blind: Despite the evidence and knowledge about the existence of several clones, the idea of human cloning never crosses his mind. Subverted, when Sarah lets him in on the conspiracy and he notes how things make sense now.
- Good Is Not Nice: He's willing to do some pretty ethically questionable things if he thinks it's likely to protect people from themselves.
- Hero Antagonist: He's trying to solve Katja's case, which puts the clones at risk of being discovered.
- I Let Gwen Stacy Die: He feels responsible for not picking up on the signs that Beth was suicidal.
- The Lost Lenore: He eventually confesses to Sarah that he was in love with Beth.
- Named After Somebody Famous: Art Bell was a longtime radio personality in the US, famous for entertaining conspiracy theories on the air.
- Old Cop, Young Cop: The Old Cop to both Beth and Angie's Young Cop note .
- One Steve Limit: Helena directly named one of her twin sons after him (the other after Donnie).
- O.O.C. Is Serious Business: Sarah had to quit Beth's job to avoid him because he knew Beth too well to be fooled much longer.
- Pet the Dog: He gives "Beth" her money back after she saves his life.
- Police are Useless: Averted. The fact that he and the other cops are actually good at their jobs makes the whole conspiracy that much more complicated.
- Secret Keeper: He knew about Beth's drug issues and that her shooting of Maggie Chen wasn't an accident; though he didn't know exactly why Beth had to kill her.
- As of 2x02, he's actively keeping the knowledge of the clones from Angie.
- Those Two Guys: Seems to be this along with Angie after "Beth" quits the force.
- Token Minority: To a certain extent; he's the only black main cast member, though there are quite a few other minorities on the Toronto PD.
- Undying Loyalty: To Beth, even after he finds out about her death. He seems to transfer this to Clone Club once he finds out about them.
- Played by: Dylan Bruce"If you told me what this was about, perhaps I could help you."
Beth's 'boyfriend', but in actuality her monitor. He notices "Beth's" strange behavior and it upsets him deeply. It is later revealed that he is an operative working for the military regarding Project CASTOR.
- Becoming the Mask: He was genuinely fond of Beth and wanted to take her away to South America. He eventually admits to Sarah that he loves her and not Beth.
- Blackmail: Supposedly, he killed six Marines in combat and tried to cover it up. The Dyad Institute seems to think this is something they can use against him, but in actuality, he is trying to infiltrate Dyad itself.
- Bed Trick: He sleeps with Sarah thinking she's Beth. Subverted when he later implies to the Dyad that he suspected she was someone else the whole time.
- Beneath Suspicion: He works for Project CASTOR, but had infiltrated Dyad as well. Beth came to realize that there was something off about him. It's implied that she discovered his deception (at least on the Dyad side of it) and was heartbroken over it.
- Bigger Is Better in Bed: Felix nicknames him 'Big Dick Paul' seconds after seeing him nude.
- Character Death: Gets stabbed by Miller, shot four times by Coady and blows up her lab with him still inside in 3x06.
- Chronic Backstabbing Disorder: Thanks to being a Double Reverse Quadruple Agent, he has betrayed and rejoined several people and factions in the story. He even betrays his main faction, ultimately sacrificing himself for Sarah.
- Crazy Jealous Guy: Averted. He doesn't seem to be particularly distraught when he finds out Sarah hooked up with Cal again. Most likely justified because of him trying to maintain his cover to infiltrate Dyad on behalf of Project CASTOR.
- Dating Catwoman: His relationship with Sarah has some elements of this.
- Double Reverse Quadruple Agent: He worked with Neolution, Dyad, and the Clone Club while really working for Castor.
- Even the Guys Want Him: Felix fawns over on how well-endowed he is.

- HeelFace Turn: He appears to join the clones' side after episode 7, despite Dyad still thinking they have a hold on him.
- HeelFace Revolving Door: Bordering on Double Reverse Quadruple Agent. He is so hard to read it is impossible to know who he is truly working with between Rachel, Leekie, Sarah, and Mrs. S. Moreover, Tony's friend Sammy indicated before his death that Paul may have his own agenda, and felt that this was important enough that the clones needed to know it. It is later revealed that he is part of the military working for Project CASTOR all along.
- HeelFace Door-Slam: Finally stays on Sarah's side and helps her to escape Castor HQ right before he dies.
- Heroic Sacrifice: After being fatally wounded by Miller, he manages to buy Sarah time to escape and uses a grenade to demolish Coady's lab, killing himself in the process.

- Majorly Awesome: His rank in the Military.

- Shirtless Scene: He gets quite a few.
- Tall, Dark, and Handsome: He stands 5'11 1/2.
- Understanding Boyfriend: He seems pretty supportive of Beth, who had a myriad of mental issues. Though there was a reason for that, as he was her "monitor" for the people who were studying her.
- Unfriendly Fire: Subverted. His story about killing six marines in Afghanistan was just a ruse to make Dyad think they could use him.

- Good Is Not Nice: She appears to have a particular disdain for Sarah (mainly because she tried to take over Beth's life), but you can't exactly say she's a bad person. Her continued pursuit of Alison and blackmail of Vic pushes her further towards moral grayness, however.
- Hero Antagonist: She's trying to solve Katja's case, which puts the clones at risk of being discovered.
- Inspector Javert: She continues prodding into the Katja case, long after Art has given up and later got mixed up with it. As of 2x06, she's using Vic to keep tabs on Alison.

- Repetitive Name: Angela Deangelis.

- There Are No Therapists: Averted. Beth has an assigned psychologist, Dr. Anita Bower, who has been giving her overlapping prescriptions.

- Embarrassing Last Name: Before he took his wife's name, he was Donnie Chubbs.
- Fake Guest Star: He's a very prominent character in Season 2 but is only billed as a guest-star. He finally gets his Promotion to Opening Titles starting the third.
- Friend in the Black Market: He becomes one in season 3 when he helps Alison run an illegal drug ring to fund her campaign for school trustee.

- I Just Shot Marvin in the Face: How Leekie dies by his hand.

- The Maiden Name Debate: He took his wife's name, see Embarrassing Last Name above
- The Mole: Alison suspects him and Aynsley to be this for her. He really is her monitor.
- My God, What Have I Done?: He feels pretty distraught after learning he was monitoring his wife as a part of a cloning experiment.
- He experiences this again when he accidentally shoots Leekie in the face.
- Obfuscating Stupidity:
- Even after Alison learns about him being her monitor, he does a hell of a job continuing to act like a betrayed husband who's supposedly protecting his kids from their alcoholic mother.

- One Steve Limit: Helena directly named one of her twin sons after him (the other after Art).

- Unwitting Pawn: He was monitoring Alison for Dr Leekie in exchange for a stipend and forgiving his student loans, but was told it was part of an extended sociological study. He didn't know she was a clone, and he didn't know that people would come into their house to examine her in her sleep.
- Ugly Guy, Hot Wife: Not ugly per se, but he's no stud. He goes out jogging in the finale because "[she] deserves better". Really, he's meeting up with Dr. Leekie. The show plays it up in that the other men on the show are California beautiful, whereas Donnie's more or less a regular guy; attractive but not a model. Then they go and put him in sagging white underpants half the time.
- Your Cheating Heart: He told Alison that he'd had an affair, but this is may be a lie to get her to drop her suspicions.

Alison's "friend" and neighbor.
- Belated Backstory: We get a flashback to her friendship with Alison long after her death in Season 5.
- Cruel and Unusual Death: In the Season 1 finale, she dies in a manner worthy of Final Destination. Her scarf gets caught in the garbage disposal, causing it to slowly choke her as it's sucked in. Alison just stands there and watches her die.
- Et Tu, Brute?: From her point of view, Alison dealt her one betrayal after another: sleeping with her husband, revealing her own affair in front of their other neighbors, and not lifting a finger while she choked to death.
- Go-Getter Girl: An older version. She was involved in a lot of community activities.
- Happily Married: Subverted. Her marriage looks happy and normal from the outside, but it's plagued with adultery. She gets a divorce in the finale because her husband cheated on her with Alison and that was The Last Straw.

- The Mole: Alison suspects her and Donnie of being this. She's actually a Red Herring Mole.
- Nosy Neighbor: Zig-Zagged. At first she seems like just a stereotypical suburban nosy neighbor, the kind who snoops in her friend's mail and asks overly personal questions.

- The Cutie: She's very sweet and completely oblivious to the conspiracy. Her appearances really brighten up Alison's storyline.
- Fat Best Friend: For Alison.
- Iconic Sequel Character: Does not appear until Season 2.
- Nice Girl: Sarah is hands-down one of the kindest, most supportive people on the whole show.

Alison's demanding, perfectionist mother.
- Jerk with a Heart of Gold: Despite her cool exterior, she really is a loving mother.
- Last-Name Basis: She only calls Donnie by his birth last name, Mr. Chubbs, despite the fact that she insisted he take Alison's surname.
- Like Mother Like Daughter: Seeing her is like watching Alison from season 1: demanding and snobby, but ultimately very loving.
- Obnoxious In-Laws: She's very dismissive of Donnie. The reason she initially refused to sell Alison her store is that she didn't want Donnie to be co-owner.

- Playing Sick: She feigns a panic attack to get Alison to come down to her store. According to Alison, she's done it before.

Some of Alison's neighbors and friends.
- Alpha Bitch: As of season two, Charity Simms.

- Played by: Évelyne Brochu"I just want to make crazy science with you in our new lab."
Cosima's French classmate who arrives as part of an exchange programme.
- Becoming the Mask: She is assigned as Cosima's monitor but genuinely falls for her and begins acting as a Reverse Mole on Clone Club's behalf.
- Bi the Way: It's a bit complicated, but she very definitely loves Cosima, and she doesn't appear to have been attracted to women at all before Cosima. Word of God says she sees herself as a case of If It's You, It's Okay.
- Cliffhanger: In the Season 3 finale, Delphine is shot by an unseen assailant and left for dead. Cosima thinks Delphine's dead in Season 4, but not only was Delphine's death not officially confirmed, but it was deliberately left ambiguous. Evie Cho claimed she was dead, but Evie would have good reason to lie, and Krystal Goderitch saw Delphine carried away, still alive, after being shot. She is ultimately confirmed to be alive in the last scene of episode 4x09.
- Clingy Jealous Girl: Even though she's the one who broke up with Cosima, Delphine spies on her and her new girlfriend Shay.
- Everyone Looks Sexier If French: Cosima at least seems to think so. And the first reason Rachel states for giving her Leekie's recently vacated post is "She's telegenic."
- Everyone Loves Blondes: People generally like her quite a lot purely from looking at her.
- Expository Hairstyle Change: In season 3 she straightens her hair. She does it after she takes over Rachel's position to look more professional. It makes her resemble Rachel a little and matches her attitude becoming colder and more pragmatic.
- Face Death with Dignity: Knowing that Nealon will make good on the threat on Delphine's life, she makes an effort to make it up to Cosima and Shay for misunderstanding them.
- Foil: To Shay. Both serve as love interests to Cosima, are connected to a faction that is opposed to the clones and are perceived as The Mole. However, unlike Delphine, Shay is most likely innocent. Shay is also a very spiritual person compared to Delphine the scientist.
- Girlfriend in Canada: She lied about breaking up with a boyfriend back home to attract Cosima's attention.
- Gratuitous French/Poirot Speak: She peppers her speech with French expressions.
- Hidden Heart of Gold: Was only really doing so because her alignment with Topside demanded she make quick, harsh decisions. Her mask of callousness begins to fade in the Season 3 finale.
- Hot Scientist: She's a scientist, played by Évelyne Brochu, who is certainly quite nice to look at.
- If It's You, It's Okay: According to Word of God, she identifies as straight, with Cosima being her exception.
- It Meant Something to Me: When her spying for Dyad is revealed, this is her reaction. It is later proven true.
- Kicked Upstairs: Being given Leekie's former title means she will no longer be working with the clones.
- Love Redeems: By the first season finale, her love for Cosima turns her to the clones' side.
- MayDecember Romance: She was involved with Dr. Leekie, who's at least twenty years older her.
- The Mole: She's Cosima's monitor. She later turns on them and begins feeding them false information, though her top priority is saving Cosima's life rather than telling them what Cosima wants them to know.
- My God, What Have I Done?: She feels horrified with herself when she learns that Rachel manipulated her in order to kidnap Kira.
- She has a similar, if a bit more subtle, reaction when she finds out that the clones were patented, and she realizes just what sort of business she was a part of.
- Gets this look on her face yet again in 3x09. Delphine interrogates Shay, as Cosima suspects Shay of betraying her to Castor. Cosima calls with the correct mole immediately after Delphine has threatened to murder Shay and make it look like suicide.
- Never Found the Body: According to Krystal, the reason no one ever found Delphine's body is because she was carried away after being shot by an unknown assailant at the end of Season Three, and she was still alive at the time this happened. Sure enough, she's shown to be perfectly alive and well at the end of 4x09.
- Nice Girl: Overall she's quite a nice person.
- Nice Job Breaking It, Hero!: Unintentionally allowed Rachel to kidnap Kira.
- Not Quite Dead: The end of 4x09 reveals that she survived her shooting, after almost a season of speculation. Granted, this point had been foreshadowed so heavily by the time it was finally confirmed that the real twist is ultimately not that she survived, but how and what she's been up to since.
- Pet the Dog: When reporting to Leekie about Cosima's contacts with other clones, she doesn't mention Kira at all.
- Obi-Wan Moment: Later when she pulls into Dyad, and aware that an assassin is waiting for her, she calmly puts her purse down before getting shot. Subverted in that she is ultimately revealed to have survived.

- Reassigned to Antarctica: Rachel later sends her to Germany to get her away from Cosima. Of course, with Bowles stepping in to undermine Rachel, who knows?
- Reverse Mole: She continues working for Dyad, but this time on behalf of Cosima.
- Stupid Sexy Flanders: The very openly gay Felix repeatedly gushes over her, especially over her hair.
- Took a Level in Jerkass: She became more ruthless and manipulative between Seasons 2 and 3. It's ultimately revealed to be a facade.
- Uncertain Doom: Not only is it initially unclear if she died in the shooting at the end of Season Three, but that uncertainty is a plot point. After nearly a season's worth of speculation among the characters themselves, it's finally revealed at the end of 4x09 that she survived.
- Undying Loyalty: Season 2 strongly implies that she will do anything and everything necessary to ensure Cosima's survival, regardless of what Cosima thinks about it or how it affects anyone else.
- Unwitting Pawn: She attempts to warn Sarah about one of the Birdwatchers defecting to the Dyad, but it turns out the information was false. When she actually warns Sarah, Rachel uses the opportunity to slip in and kidnap Kira.
- Violently Protective Girlfriend: When she believes Shay is a mole for Project Castor spying on Cosima, she threatens to cut her feet and let her bleed out in her bathtub.

- Alliterative Name: Scott Smith.
- Brainy Brunette: He's brown-haired, and one of the smartest characters in the show.
- Genre Savvy: He knew Cosima had been studying clones for some time, based on the DNA she shared with him. Though he's not quite savvy enough to realize Cosima herself was the "324B21" specimen they've been analyzing the whole time.
- Girl-on-Girl Is Hot: Has a less-than-subtle reaction as he watches Cosima and Delphine kiss. This is later lampshaded in 3x09 by Cosima when she introduces him to Shay, her current girlfriend.Cosima: He loves lesbians.Scott: Well, I....Can I sequence your genome?
- Hollywood Nerd: Has an extensive science fiction collection, and is an avid board game player. Both of these end up being plot points in the third season.
- Hopeless Suitor: To Cosima. Towards the end of Season 2, though, he appears to bear no ill will about having his crush thwarted, and he responds to Cosima's clone confession with grace and kindness.
- Incompatible Orientation: He had a crush on Cosima and even attempted to flirt with her in Season 1.
- Kindhearted Cat Lover: He has a cat named Denise.
- Promotion to Opening Titles: As of season 4.
- Scale of Scientific Sins: He's shocked to learn that Cosima herself is the clone that they've been studying and trying to save. He then says that working with her is an honor. This may be because he'd viewed it solely as an interesting problem and now has to view her as human.
- Secret Keeper: He discovers that the stem cells used to treat Cosima must have come from a daughter or niece to be viable, which of course means Kira. Delphine demands he keep this information to himself, which makes Scott uncomfortable given his affection for Cosima. He's let off the hook early, though, as Cosima finds out anyhow in the next episode.
- Smart People Wear Glasses: Scott certainly does.
- Those Two Guys: With Hell Wizard.
- Undying Loyalty: He seems to do Cosima's bidding regardless of how little she offers him in terms of information or kindness, mostly because of the torch he carries for her. They do become closer at Dyad, however, and Scott seems to pledge himself to helping Cosima even though she's clearly in love with someone else. After his positive reaction to her 'coming out' as a clone, it seems he might be the truest ally she has. By the finale this extends to the other clones as well, since he helps Cosima break Sarah out of the institute.
- Played by: Ksenia Solo
A soulful and compassionate holistic healer with a great sense of humor whom Cosima starts dating after breaking up with Delphine. They meet via the Sapphire dating app, at Felix's suggestion.
- Foil: To Delphine. Both serve as love interests to Cosima, are connected to a faction that is opposed to the clones and are perceived as The Mole. However, unlike Delphine, Shay is most likely innocent. Shay is also a very spiritual person compared to Delphine the scientist.
- Good-Looking Privates: She's ex-military.
- Hair of Gold, Heart of Gold: Has golden blond hair and a gentle soul.
- Hidden Depths: Delphine's file on her contains a photo of Shay in military uniform.
- Lipstick Lesbian: She's very feminine, and has not given any sign of being attracted to men.
- The Mole: The possibility has been brought up by Delphine, though it's difficult to say if it's just because she was simply obsessed with Cosima post-breakup. While Cosima ultimately agrees with Delphine's reasoning, it turns out she's a Red Herring Mole.
- Nice Girl: She's very sweet and easygoing.
- Sensual Slavs: Played With. She's a very attractive woman with a Russian surname (and played by a Russian actress) but doesn't use the Slavic accent typically associated with this trope.
- Understanding Girlfriend: She goes out of her way to make Cosima happy and comfortable.
- After being harassed by Delphine not to mention accused of being a spy and threatened with murder she's a bit less understanding.

- Nice Hat: He wears a trucker hat, which Helena holds onto long after leaving. She is seen caressing the hat before she is captured by the Military in the Season 2 finale.

- Imaginary Friend: It only exists in Helena's imagination.
- Non-Human Sidekick: And non-real to boot.
- Poisonous Friend: Well, more like venomous, but yeah.
- Small, Annoying Creature: Helena often seems to have created Pupok just to have someone to argue with.
- Talking Animal: Voiced by Tatiana Maslany, who also does the sound effects.
- Talking to Herself: Not that this is anything new for Maslany.
- Walking Spoiler: It can't be helped since Pupok exists only in the mind of another Walking Spoiler. Indeed, even knowing that Pupok shows up in the television series is a spoiler for people who have read the comic but not yet seen season two.
